SAMUEL FRIEDMAN AND MAX OHLBAUM, OF NEW YORK, N'. Y.

FIBER COMB.

Application led March 12, 1921.

To all whom it may concern:

Be it known that we, SAMUEL FRIEDMAN and Dr. MAX OHLBAUM, citizens of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Fiber Combs, of which the following is a specification.

This invention relates to fiber combs, the object thereof being to provide an improved article of this type which will be serviceable in use and which may be manufactured and produced at a minimum of expense.

Due to the fact that there is always a large demand for cheap and sanitary combs for use in public places, and which after use may be thrown away or destroyed, thus doing away with the so-called public combs used over and over again and which are recognized as unsanitary and unhealthy, the essential purpose and object of our improvement is to provide an inexpensive but sanitary article which may be used in quan` tities in public lavatories without great expense. The necessity of having to use a comb previously used by other persons will thereby be avoided.

Other objects of our invention will appear in the following description thereof, reference being had to the accompanying drawing forming a part of this specification, wherein like reference characters indicate corresponding parts in the several views and wherein Fig. l is a plan view illustrating a blank for a comb; Fig. 2, shows an enlarged cross-section thereof; Fig. 3 is a side view illustrating in part a completed comb; Fig.

A4f is an enlarged section as on line 4--4 of Fig. 1; and Figs. 5, 6, and 7 show modified forms thereof.

In its preferred form herein shown and described we provide a comb stamped from a blank sheet 5 composed of a material that is practically waterproof without any special treatment of its surfaces. One such material is fiber or other relatively dense non-porous material, such as insulating fiber. In practice the fiber sheets are treated during their preparation with some suitable preparation or substance so that the sheets are waterproof. The comb 6 is stamped or cut out from the blank 5 and is thereupon ready for immediate use without necessitating the application of varnish or the like, or the impregnation of the surfaces with waterproofing material.

terial before completion of the blank sheet renders this eXtra step unnecessary. yThe blank may comprise if desired several layers, 8 and 9 of liber stock, intimately and integrally associated, during the manufacture thereof, as illustrated in Fig. 4, without the need of any intervening substance to stick or retain the layers together, the construction of theblank being such that a comb of great durability, strength, and sufiicient rigidity is obtained, thus resulting in a very practical and efficient expendable article.

Heretofore all sanitary combs of the present general type which have been put on the market have been so expensive to manufacture that the very object for which they are designed, namely, the provision of a very cheap, but satisfactory article, has been prevented. In order to make a comb such as this successful commercially, it is absolutely necessary that every unessential step beeliminated from the process of manufacture. It is recognized that there are two important requisites of a sanitary comb, namely that it be manufactured of cheap material, and as a finished product be sufficiently waterproof to render the same impervious to the deleterious effects of water.

Heretofore one of the main disadvantages of sanitary combs, made from paper,fcard board, or other relatively porous stock resides in the necessity of treating the finished article with a suitable preparation to render the same impermeable, such process being comparatively expensive and thus an obvious commercial drawback. For instance it has been attempted to make sanitary combs from paper, cardboard, or papier mch, the blanked article being coated, varnished, shellacked, or otherwise treated after the completion of the comb in order to render the same impervious to the eHects of moisture. This coating or impregnating of the surface of the comb has been found to be a commercial disadvantage due to the comparatively great expense incident thereto.

Thus by virtue of our invention these disadvantages are done away with, and we accomplish the same by constructing a comb of fiber or other relatively dense and nonporous substance such as is often employed for instance in the production of insulating materials and which raw material prior to the blanking out of the comb is preferably treated in any suitable way thereby to render the finished article thoroughly impermeable and Waterproof. The waterprooting clienti" cal or material is incorporated. in the liber pulp, and hence'the liber sheets `formed vtroni the pulp are thereb'y rendered thoroughly Waterproofed by virtue of this chemical treatment. Thus after the fiber or ma- 'terial to be used for making the blanks is treated with such preparation and a't'ter the formation of the blank sheet, the comb mayr be stamped lout by means oi suitable dies, or otherwise formed therefrom. The Cornpleted comb is then ready 'for use and it will be seenthat by means of this simplified process, the lseparate step of varnishing, shellacking, coating, or impregnating is entirely eliminated and therefore itvsill be obvious that the ultimate cost oi'our completed comb will be very materially reduced, By 'virtue `of the fact that the raw material or ber from which the blank is produced for stamping out the comb, is usually first treated in themanner above indicated, the eempleted comb therefore will be more ellentively impervious to the effects ot moisture and hence in a single Vstep ive accomplish what has hitherto required at least two steps, and at the same time our improved sanitary combmade from cheap fiber is manufactured at a greatly reduced cost.

In order to secure an increased rigidity or stiffness in 'our improved sanitary comb, the same may be readily acconujilshed by providing the comb G, as illustrated in lif y. 5, with a groove l0 of any suitable length, width, and depth, the same being eli'ected as by stampingor compressing a portion of the comb to form the groove. Or the comb may be reinforced by providing a eorrugation or ridge 11 as shown in Fig. 6 comprising a 1 ,essere depression on one sith.` und :i bulging or ribbed portion on the opposite sido oi" the womb. In this manner therefore the tomb is readily, inexpensively, and integrally reinforced or stilfened without neressitating the use oif a separate or hidepeiuleul; strip ol metal or other material, the eomparative oost ofwhioh method would do away with the essential purpose of my invention; namely to provide a cheap butv eiiirient comb.

Although we have described our invention in its preferred form, it is to be understood that We do not limit ourselves to the present preferred embodiment herein shown and described, except in so tar as defined in the claims and embraced within the scope thereof.

le claim as our invention:

l. As an article et manufacture a comb eut from ablank having non-coated surfaces impervious to moisture, said comb having an outer surface provided with a lengthwise extending depressedv portion.

2. As an article ot manutzutture, a Comb stamped from a blank ot fiber treated with a waterproofing substance prior to the com-A pletion of the blank, thereby to render the surfaces of the comb substantially impervious to the eifects oil moisture.

3. As an article of manutarture, a comb lormed 'troni a blank oit writerprooied tiber material, said comb being so ilornied as to have the surfaces thereo'lf substantially 1npervious to moisture without necessitating the Coating of the surfaces. i
